A quick and sweeping lockdown of all Republic elementary and middle schools ended midday Friday without incident.

Superintendent Chance Wistrom said a woman walked into an elementary and reported that she had been threatened by someone with whom she has a relationship.

He said neither the woman nor the individual she is in a relationship with are students or school employees.

"I don't know if it was proximity, if (she) was here anyway or if she was seeking refuge," he said.

Wistrom said the district decided to take immediate precautions, alerting the Republic Police Department and issuing an external lockdown of all elementary and middle schools in the vicinity.

The lockdown meant roughly 3,000 students — and the teachers, principals and other staff that work in those buildings — were not allowed to go outside.

Josey McPhail, spokeswoman for the district, said "normal classroom routines" were maintained during the lockdown. It was issued shortly after 11:15 a.m. and was over within 30 minutes.

"The Republic Police Department has deemed the potential threat has been resolved and is not a threat to our students or staff," she said. "An outside patron conflict resulted in this precautionary perimeter lockdown."
